TIA/EIA to Publish Optical Fiber Cabling Components Standard

Orlando, FL. — On March 3, the TIA TR-42 Engineering Committee unanimously approved the publication of the TIA/EIA-568-B.3 Optical Fiber Cabling Components standard. This document is part three in a series of telecommunications standards being developed to supersede the TIA/EIA-568-A Commercial Building Cabling standard. When complete, the third edition of TIA's Commercial Building Telecommunications Cabling Standard will include:

TIA/EIA-568-B.1 (‘568-B.1), General Requirements
TIA/EIA-568-B.2 (‘568-B.2), 100 Ohm Balanced Twisted-pair Cabling
TIA/EIA-568-B.3 (‘568-B.3), Optical Fiber Cabling Components

The content of ‘568-B.3 addresses the mechanical and transmission performance requirements of optical fiber cable, connecting hardware, and patch cords. According to TIA TR-42.8 committee member, Christine Klauck from The Siemon Company, the two most significant enhancements over ‘568-A include the recognition of 50/125 ÿm multimode fiber and the use of small form factor (SFF) fiber connectors. The SFF connector designs are physically specified to satisfy the requirements of their corresponding TIA Fiber Optic Connector Intermateability Standard (FOCIS) document. According to Ms. Klauck, "This standard recognizes emerging optical fiber cabling technologies that will serve to expand the capabilities of fiber cabling in buildings and campuses and fuel increased acceptance of Fiber To The Desk (FTTD)."

The TIA's decision to publish the ‘568-B.3 standard prior to the completion of ‘568-B.1 and ‘568-B.2 was motivated by the need to immediately raise industry awareness of the new fiber component specifications. Issues in parts one and two that are subject to final review include the adaptation of the permanent link model, improved measurement accuracy, and category 5e multi-pair cable specifications. It is anticipated that ‘568-B.1 and ‘568-B.2 will be approved for publication within the next six months.
